I'm confused. You say you don't agree with me, then give an example that confirms what I said (Replace Guest OS with machine memory map as appropriate). What I don't agree is the fact that emulating huge amount of physical address space is not immediatly useful. Ah, ok. I meant

Also note that changing variables from int to long have strictly no impact on 32 bits host machines, then won't help emulating more than 2 GB of RAM. Another variable type (target_phys_addr_t ?) should be used instead. This patch should be restricted to 64-bit hosts. I don't think it's
